P&P 2010 wound healing k
Question | Answer |
---|---|
a wound that is a result of a blow, and has ecchymosis (bruising) is what type of wound ? | contused wound (contusion) |
a wound that was caused by a sharp instrument, an has clean edges is ? type of wound | incised wound (incision) |
a scrape, from friction, is an ? type of wound | abraded wound (abrasion) |
a wound that is a tear in the skin and the edges are uneven is what type of wound | lacerated wound (laceration) |
a stab wound is a | puncture |
puncture wound deep in to tissues is what type of wound | penetrating wound |
where there is minimal tissue damage – cells recover & return to normal function is what type of healing | resolution |
the replacement of damaged cells with identical ones (mitosis) is called | regeneration |
cells that Multiply throughout life are called | Labile cells |
cells that Multiply when necessary - Regenerate well, but slowly, eg. bone cells, liver cells are called | Stable cells |
cells that have poor regeneration are | Voluntary & Involuntary muscle |
cells that have no regeneration abilityh - e.g. cardiac muscle, neurons in CNS are called | Permanent cells |
Process of using connective tissue to complete | repair |
Amount of ? required depends on severity and type of wound | repair |
healing where edges closely approximated is called | Primary 1st intention – |
– a wound where the edges cannot be brought together is called | (Secondary) 2nd intention |
the late late closure of a wound is called ? In the healing classification | Tertiary intention |
What phase of repair is it is clotting and inflmation is present after sugerty (3 – 4 days) | Initial Phase (3 – 4 days) |
what phase of repair is it when Capillaries bud to nourish developing cells and Fibroblasts secrete collagen (5days- 4 weeks) | Granulation Phase (5 days – 4 weeks) |
what type of tissue is very vascular & delicate | Granulation tissue |
what stage of repair is it when the Collagen fibres shorten & the ‘scar’ diminishes in size (may take several months) | Maturation (may take several months) |
what type of scar is avascular & strong | Mature scar |
to Dilute toxins & irritants, Deliver nutrients, Form physical barrier is the purpose of ? | wound exudate (drainage) |
Type of ? depends on severity of injury, location & presence of other substances | drainage |
exudate that is clear, and watery is called | Serous |
exudate that is clear,and thick is called | Fibrinous |
exudate that is red in colour (hemorrhagic – contains RBC’s) is called | Sanguineous |
exudate that has a large number of WBC’s, dead & living microbes, liquefied dead cells | purulent |
exudate that contains mucus is called | Catarrhal |
Youth,Good nutrition, Vitamins A & C, protein, zinc, Adequate hemoglobin,Effective circulation, Clean, undisturbed wound,No complications are ? | Factors that Promote Healing |
Extent of injury - Large, open areas more difficult, Age – older adult, Impaired circulation, Collagen less pliable,Clotting impaired with reduced liver function, are ? | Factors that Impair Healing |
Inadequate blood supply -decreased supply of nutrients and decreased removal of exudate & debris, - Impaired oxygenation Alter synthesis of collagen & formation of epithelium, are ? | Factors that Impair Healing |
Smoking -Reduces functional hemoglobin, Wound Stress / Mechanical Injury -Damage to new granulation tissue are ? | Factors that Impair Healing |
Wounds healing by secondary intention can be classified: | cause -surgical, nonsurgical, acute, chronic |
Wounds healing by secondary intention can be classified: | By Depth of Tissue Affected - superficial - only epidermis - partial thickness - epidermis & dermis - full thickness - beyond dermis |
skin with a defined area of persistent redness (in darker skin tones - red, blue or purple), Temp - hotter or colder than surrounding skin, Tissue consistency - may be firm or boggy, Pain or itch is what stage of a pressure ulcer | stage I |
tissue with partial thickness skin loss, superficial, looks like an abrasion, blister or shallow crater is what stage of an pressure ulcer | stage II |
tissue that has Full-thickness skin loss, Damage to or necrosis of sc tissue, and has a Deep crater is what stage of pressure ulcer | stage III |
tissue that has Full thickness skin loss with extensive damage, increased tissue necrosis, Damage to muscle, bone & supporting tissues is what stage of pressure ulcer | stage IV |
